MACHINE FOR MANUFACTURE OF EXCELSIOR.

SPECIFICATION forming part of Letters Patent No. 561,393, dated June 2, 1896. Application filed May 25, 1895. Serial No. 550,703. No model.) Patented in England April 3, 1895,110. 6,892.

T0 at whom, it may concern:

Be it known that I, CAESAR I-IAss, a citizen of the United States of America, and a resident of 261 Burdett Road, Limehouse, London, England, have invented certain new and use ful Improvements in and Connected with Machines for the Manufacture of Excelsior or Similar Products, (patented in Great Britain, No. 6,892, dated April 3, 1895,) of which the following is a specification.

The object of my invention is improvements in and connected with machines for the manufacture of wood wool (excelsior) or similar product, such as wood fiber, used for the manufacture of paper-pulp; also for manufacturing matches and match-splints and the like, whereby greater efficiency of action of the machine is insured and a larger quantity of material produced.

The main features of my invention are constructing a continuous row of metal slats riveted to a broad band arranged over pulleys in such a manner that on a straight line each slat will support its neighbor edgewise and thus in conjunction with the slides form a complete solid table to give suiiicient resistance to the pressure of the knives against the wood; providing a small roller suspended by a frame for each piece of wood which is being worked to rest against such roller, which is put so near the working surface that when the piece of wood is cut down to a residue of about half an inch the roller will be forced up by the wood and the latter be thrown out of the machine automatically, the roller returning to its working position by a spring; providing a knife-cleaner placed as close as possible to the part where the wood is out, such knife-cleaner consisting of a wheel of wood or other material softer than iron, and is driven at a far greater speed than the knives, but in the same direction, and will thus, by coming in contact with the latter, clean them from any chips which might remain thereon.

My invention will be clearly understood from the following description, reference being had to the annexed drawings, in which- Figure 1 is a longitudinal sectional view of a machine through the line a h of Fig. 2. Fig. 2 is a plan of the machine. Figs. 3 and 4 are sections looking toward either end of the machine through thelines c d and e f of Fig. 1, respectively. Fig. 5 is an edge view,on an enlarged scale, of a portion of the broad band, having affixed thereto the metal slats and plates and showing a multiple groovingtool and a plain-edged knife in position. Fig. 6 is a plan, also on an enlarged scale, of some of the metal slats and plates, showing the position they occupy one with the other and with three plates removed to show the construction of the corners of the metal slats. Fig. 7 is a section on line g h of Fig. 6, showing the band, metal slats, plates, and guides combined.

A is a framing, to which is affixed, in suitable bearings B, pulleys OD, carrying an endless band E, to which are attached, by rivets or otherwise, metal slats F F, each slat being of greater length than the width of the endless band E, and arranged next each other around the band E, but with a narrow space between each. On each slat F, and preferably at those parts outside the endless band E, I affix, by screw-rivets or otherwise, steel or hard-metal plates G, these being of such a degree of hardness as to withstand for a length of time the friction created when the machine is at work, and these plates G, being attached to the slats F by screw-ri vets or similar appliances, as at Fig. 6, can, when worn down, be easily renewed without destroying or interfering with the slats F.

Oertain'slats F and plates G, preferably at equal distances apart, are provided with holes or slots H, Figs. 5, 6, and 7, for containing the groovers or scorers I and knives I used for grooving or scoring and cutting the wood under operation, said groovers or scorers and knives being adjustable as to depth or angle of cut by a screw-pin J, which engages with a projecting portion K, attached to the under part of the slat, through which the hole II is cut.

The groovers or scorers I, which maybe of any construction, but preferably of theform described in the specification of my application for United States Patent, filed May 25, 1895, under Serial No. 550,704, are arranged alternately, so that the wood under operation is first grooved or scored by the groovers or scorers to 'the depth and width required, according to the nature of the product required,

and in the case of grooving the wood the remaining projecting parts between the grooves are out off by the knife following, so as to make the wood flat or comparatively flat on the operative surface ready for the next grooving-tool to act upon it; but in the case of simply scoring the wood the width required the knife would slice off to the desired depth the whole surface of the wood to produce the wood wool (excelsior) or other product, or each groover or scorer and knife may be combined in one article, as is well known.

The metal slats. F are formed with projecting corners L for each one to be in touch with its neighbor at those points only when they are in a straight line. Thus they will support each other and by their conjunction with the plates form a solid band sufficient to form resistance to the action of the groovers and knives when at work and so prevent great strain upon the machine. In the event of any of .the slats not touching its neighbor a simple knock by a hammer at the projecting corner will force it into contact with its neighbor.

On the under or inner side of the slats F and outside the edges of the belt E, I affiX segments M, having an opening lengthwise somewhat of U shape, and at about the outside edge of the slats I affix other segments N-,these being of flat shape; but they may have the U -shaped opening lengthwise. These segments are in close proximity to each other endwise and form guides all around the inner side of the slats, and being angled-faced at their endscan partake of the circular shape of the pulleys O D when passing around them.

The guides M N run upon tracks P Q, the tracksvP being arranged on each side on an inner framewor k A of the machine and the tracks Q upon the outer framework A of the machine, the working surface of the tracks beingin line with the upper edge of the pulleys C D, so as to form a solid table for the cutting to be effectedon, and by the shape of the guideM- and track P all side motion of the band is obviated, and consequentlythe cutters are always in the proper line and position for working Adjacent to the hoppers or'fe'ed-entries R of the machine is a hinged frame S, carrying rollers T T or other appliance, against which one end or ends of the piece or pieces of wood under operation abuts, and when .a piece of wood is cut'down by the knives to about one half inch in thickness, or just-below the center line of the roller T, the knives acting on the wood meeting with no resistance force the piece of wood under the roller, and carrying it. along to the end of the machine automatically ejects it through the opening U clear of the machine, a. fresh piece or pieces of wood taking itsplace, to be acted upon by the groovers or scorers and knives following. The rollers are kept totheir working position by suitably-arranged springs T and limited in their downward movement by the stop T or other device;

The roller-frames, instead of being hinged, as shown, may be arranged perpendicular or otherwise and in other frames, so as to be slid up by the wood when sufficiently cut down, the rollers returning to their working position by springs. I also arrange as near as possible to the place where the wood is cut a knifecleaner V, which consists of a roller or wheel of wood or other material softer than the knives or cutters, said roller or wheel V being arranged on a hinged frame WV, and by gearing or belting X X and pulleys Y Y Y Y driven from the main driving-axle Z to a far greater speed than the knives motion, but in the same direction, so that it will, by coming in contact with the knives, clean them from any chips or other debris which might remain thereon.

The pulley-bearings B are so arranged as to be adjustable for taking up any slack of the endless band, and preferably by the means shown in Fig. 1, by simply loosening the nuts e e and shifting the bearing by moving the screw f.

g g are bearings for the axle 71 carrying the knife-cleaner frames NV and pulleys.

The pulleys C D are driven at one side of the machine from belting attached to a fastpulley 1' fixed on theaxle Z of the large pulley D.

n is the loose pulley.

The machine is fed through the openings or hoppers R by hand or other means of pressure with pieces of wood to a given size between the pulleys above the tracks, and the operator holding the top piece or pieces of wood down to give sufficient resistance to the knives, which cut the bottom piece of wood from underneath, or a number of pieces of wood may be arranged one above the other to create weight to give the necessary resistance. In the first instance just mentioned the blocks of wood when out to athin strip would be automatically discharged, as heretofore described; but if one, two, or more blocks are placed upon thevblock being out then said latter-named block would be entirely eaten up and there would be no need for the roller T. The product-wood wool, excelsior, or the likeis guided to outside of the machine by chutes l, which are arranged directly under the cutting portion of the machine and with their upper edges at or near the inside tracks and their lower edges outside of the machine, so that the material as it is cut is prevented from falling on the band and thus interfering with the action of the machine.

m is a metal plate having openings corresponding to the hoppers R and arranged above the knife-band to give steadiness to the wood and prevent it being moved sidewise from its position during the working of the knives.

Should occasionrequire, such as when work ing hard wood, thatextra stability be given to the band, another set of guides may beaffixed to the upper or outer portion of the band or plates to runon tracks arranged under the top of the machine, for which provision is made by extra holes inthe band or plates.

By the improvements herein set forth wood wool (excelsior) or similar product of any degree of thickness and width can be produced in a rapid and comparatively inexpensive manner.
